* gsm_utils: call gnutls_global_init() as constructorAlexander Couzens2018-05-021-0/+19
| | | | | | | | | | gnutls_global_init must be called at least once for gnutls < 3.3.0. It doesn't hurt calling it twice, except a reference counter is increased. gnutls >= 3.3.0 will call it automatic. Fixes: OS#2986 Change-Id: I241b6ae5aa8df13dd78f04658cf0953e9561c9e2

| | | | | | | | | | | | | In recent Iaa20c59f624fbdc69a018cabd0f7e9c5a1389519 I fixed one missing init issue and didn't notice the N other similar ones right next to it. Also fix the remaining missing inits.

* RSL/LAPDm: Not all RLL message are "transparent"Harald Welte2018-04-192-4/+21
| | | | | | | | | | 3GPP TS 48.058 has a very clear definition of which messages are "transparent" and hence have the T-bit == 1. This is *not* just all RLL messages, but basically only RLL_DATA.{ind,req} and RLL_UNITDATA.{ind,req}. All other messages are non-transparent.

* add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr2018-04-186-98/+216
| | | | | | | | | | | | | | | | | | | | Provide comprehensive API to obtain string representations of Cell Identifiers and -Lists. Change gsm0808_test.c to use the new functions (which simplifies the output a bit), so that we don't duplicate printing code in gsm0808_test.c, and so that the not-so-trivial printing code is also tested. In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and truncation behavior. The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of cell identifiers, is that even though the maximum is 127 elements, a list of more than a few elements is hardly ever expected in practice (even more than one element isn't actually expected: either "entire BSS" or a single LAC). It is thus useful to log the entire list when it shows up in Paging and Handover. Change-Id: I9b2106805422f96c5cc96ebb9178451355582df3
* tlv: add TLV_GET() and TLV_GET_MINLEN()Neels Hofmeyr2018-04-181-0/+21
| | | | | | | | | | | | | | | | | | | | Rationale: so far we use code like if (TLVP_PRESENT(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS)) { val = TLVP_VAL(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); len = TLVP_LEN(&tp, VERY_L0NG_ENUM_VALUE_NAME_TH4T_NEVER_EMDS); } This is a) very long and b) prone to picking the wrong name one of the three times, which would use the wrong length or val without necessarily being noticed. A safer and shorter, more readable pattern is: struct tlv_p_entry *e = TVLP_GET(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); if (!e) return -ENOENT; hexdump(e->val, e->len); Change-Id: I445de17fc2daa3ab051f5708dd0cc185b23dc048

* protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSDVadim Yanitskiy2018-04-172-2/+0
| | | | | | | | | | | | According to the GSM TS 04.07, section 11.2.3.1.1 "Protocol discriminator", bits 1 to 4 of the first octet of a standard L3 message contain the protocol discriminator IE. Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e. 0b10001, that requires 5 bits, and moreover it is not documented anywhere. Let's drop it.

* test_gsm0808_enc_dec_speech_codec_with_cfg: initialize properlyNeels Hofmeyr2018-04-151-7/+7
| | | | | | | | | | | | | | The uninitialized members of enc_sc sporadically hit address sanitizer failure during gsm0808_test, like: ../../../../src/libosmocore/src/gsm/gsm0808_utils.c:187:8: runtime error: load of value 13, which is not a valid value for type '_Bool' ../../../../src/libosmocore/src/gsm/gsm0808_utils.c:191:8: runtime error: load of value 119, which is not a valid value for type '_Bool' How the test survived so long is a mystery to me; as soon as some uninitialized members would by coincidence not be zero, the test should always have failed at OSMO_ASSERT(memcmp(&enc_sc, &dec_sc, sizeof(enc_sc)) == 0).

* add gsm0808_{enc,dec}_cell_idNeels Hofmeyr2018-04-135-12/+280
| | | | | | | | | | | | | | | | | | | Clarify semantics and micro-optimise for the case of single Cell Identifer IEs. Test in gsm0808_test.c So far we have gsm0808_enc_cell_id_list2(), but there also exist instances of single Cell Identifiers (3GPP TS 48.008 3.2.2.17). It is possible to decode the same using the cell identifier list API, but this forces the caller to also keep a full struct gsm0808_cell_id_list2 with all its 127 entries around. E.g. for handover, there are two Cell Identifiers (Serving and Target); I'd need two full cell id lists for each, and these would be dynamically allocated for each handover operation, whether it uses them or not.

* add tlv_parse2(), capable of multiple instances of the same IENeels Hofmeyr2018-04-134-24/+83
| | | | | | | | | | | | | | | Allow passing multiple struct tlv_parsed in an array, to allow parsing as many repeated IEs as are expected by the caller. From tlv_parse(), call tlv_parse2() with dec_multiple = 1 to yield the previous behavior. tlv_parse() remains valid API. An example of multiple IEs is the BSSMAP Handover Request, containing Cell Identifier (Serving) and Cell Identifier (Target), both defined by 3GPP TS 48.008 3.2.2.17 with identical IE tags; both are mandatory.

* add gsm48_reject_value_namesNeels Hofmeyr2018-04-093-0/+38
| | | | | | | | | | | | | | There seems to be quite some confusion / overlap between enum gsm48_reject_value, gsm48_gsm_cause and gsm48_gmm_cause. I tried to go with gsm48_gsm_cause_names[], but e.g. GSM48_REJECT_CONGESTION is not represented. Instead of attempting to mix/merge those enums, provide a separate value string array for enum gsm48_reject_value.

* add osmo_fsm_inst_update_id_f()Neels Hofmeyr2018-04-094-22/+97
| | | | | | | | | | | | | | | | In the osmo-msc, I would like to set the subscr conn FSM identifier by a string format, to include the type of Complete Layer 3 that is taking place. I could each time talloc a string and free it again. This API is more convenient. From osmo_fsm_inst_update_id(), call osmo_fsm_inst_update_id_f() with "%s" (or pass NULL). Put the name updating into separate static update_name() function to clarify. Adjust the error message for erratic ID: don't say "allocate", it might be from an update. Adjust test expectation.

* fsm: id: properly set name in case of NULL idNeels Hofmeyr2018-04-093-19/+4
| | | | | | | | | | Since alloc relies on osmo_fsm_inst_update_id() to set the name, never skip that. In osmo_fsm_inst_alloc(), we allow passing a NULL id, and in osmo_fsm_inst_update_id(), we set the name without id if id is NULL. Change-Id: I6d6b09a811b82770818f19b189a57d9fc4a8133b

| | | | | | | | | | | | | | | | | | Place id and name testing in its separate section, test_id_api(). Add a test that actually allocates an FSM instance with a NULL id, which is allowed, but uncovers a bug of an unset FSM instance name. osmo_fsm_inst_name() falls back to the fsm struct's name on NULL, but osmo_fsm_inst_find_by_name() fails to match if the instance's name is NULL (and until recently even crashed). Show this in fsm_test.c with loud comments. Add test to clear the id by passing NULL. Add test for setting an empty id. Add test for setting an invalid identifier (osmo_identifier_valid() == false).

* osmo_fsm_inst_find_by_name(): guard against strcmp(NULL)Neels Hofmeyr2018-04-091-0/+5
| | | | | | | | | | | | | | | | | | strcmp() *must not* be passed NULL pointers, or we hit: ../../../src/libosmocore/src/fsm.c:123:8: runtime error: null pointer passed as argument 2, which is declared to never be null ASAN:DEADLYSIGNAL (Or, alternatively, a segfault.) If any of the search string or an FSM instance's name string should be NULL, simply never match. Technically, an FSM should never have a NULL name, but a current bug actually allows this (pass NULL id to alloc), which will be addressed by an upcoming patch. To test for it, we need to first make sure this here doesn't segfault. Change-Id: I2e5f82c06d1a4727bd93e955366e3b62b2df1b32
* fsm_test: terminate the main loop instead of exit on timeoutNeels Hofmeyr2018-04-092-2/+7
| | | | | | | | | | | | | | | In fsm_test.c, we have FSM instance cleanup after the select main loop, but we exit(0) in the timer cb; hence the final code is never called. Rather clean up the instance and hence also test that, by using a global flag to exit the main loop upon timeout. Adjust expected stderr output. BTW, in a subsequent commit, I want to move the fsm instance id testing to below the main loop, to more clearly group the tested bits. Change-Id: Ia47811ffcc1bd68d2630c86be7ab98fc1f338773
* add osmo_quote_str(),osmo_quote_str_buf() and testNeels Hofmeyr2018-04-094-0/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | Rationale: with osmo_escape_str(), you get the escaped contents of the string, but not so graceful handling of NULL strings. The caller needs to quote it, and for NULL strings not quote it. osmo_quote_str() is like osmo_escape_str() but always quotes a non-NULL string, and for a NULL string returns a literal NULL, i.e. it should (tm) give the exact C representation of a string. That's useful in testing, to show exactly what char* situation we have, without jumping through hoops like if (str) printf("\"%s\"", osmo_escape_str(str, -1)); else printf("NULL"); Copy the unit test for osmo_escape_str() and adjust. To indicate that the double quotes are returned by osmo_quote_str(), use single quotes in the test printf()s. I considered allowing to pick the quoting characters by further arguments, but that complicates things: we'd need to escape the quoting characters. Just hardcode double quotes like C.

| | | | | | | | | | | | | | | | | | | | | | | After investigating osmo-msc showing this log message and looking at the code, it's a bit difficult to find out what's going on in the code: socket.c:224 unable to bind socket: (null):0: Protocol not supported The root cause was not yet found, but probably SCTP is not enabled in the kernel of the host running it. The cod eis most probably failing during socket() and not due to bind error as the log says, so let's print an error if socket() fails. Then, if setsockopt fails, we want to still keep trying in case an extra addr was offered by addrinfo_helper. It is definetly wrong to continue if setsockopt fails, because then we are skipping the bind(), which is a fundamental part of what osmo_sock_init2 does. Then, let's print the bind error when it really happens, and re-write the extra log at the end if we reach the point at which no suitable addr is found.

* ctrl: fix deferred commands (and hence fix osmo-bts-sysmo 'clock-info' cmd)Neels Hofmeyr2018-04-055-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CTRL interface has a ctrl_cmd_def_* API that allows deferring a CTRL command reply until later. However, the command handling currently fails to acknowledge this and deallocates the struct ctrl_cmd anyway. Fix: in struct ctrl_cmd, add a defer pointer to be populated by ctrl_cmd_def_make(). A cmd thus marked as deferred is not deallocated at the end of command handling. This fix needs no change in calling code. (Another idea was to return a different code than CTRL_CMD_HANDLED when the command is to be deferred, but that would require adjusting each user of ctrl_cmd_def_make(). The implicit marking is safer and easier.) Show that handling deferred commands is fixed by adjusting the expectations of ctrl_test.c's test_deferred_cmd() and removing the now obsolete exit_early label. One symptom of the breakage is that osmo-bts-sysmo crashes when asked to report a trx's clock-info, which is aggravated by the fact that the sysmobts-mgr does ask osmo-bts-sysmo for a clock-info. The crash appears since Id583b413f8b8bd16e5cf92a8a9e8663903646381 -- it looked like just fixing an obvious memory leak, which it did as shown by the unit test, but deferred ctrl commands actually relied on that leak.

* gsm0480: drop messages with incorrect data lengthVadim Yanitskiy2018-04-041-9/+12
| | | | | | | | | | If either an INVOKE, either a RETURN_RESULT component has the data with incorrect length (see Annex A, 3GPP TS 04.80), the whole message is probably incorrect. Let's drop such messages instead of silent truncation. Change-Id: I2a169b0b84aa26ea2521edd55ff005c27ae6d808
* gsm0480: copy the raw USSD data, its DCS and lengthVadim Yanitskiy2018-04-043-10/+32
| | | | | | | | | | | | | | | | | | As it was already documented before, the 'ss_request' struct has a rudiment of deprecated 'ussd_request' struct - the 'ussd_text' field. It represents the data either of an INVOKE component, either of a RETURN_RESULT component, encoded as ASCII in case if DCS is 0x0f (i.e. decoded by the code itself), otherwise raw bytes 'as is'. Previously, there was no possibility to distinguish between ASCII and raw bytes with different DCS. Moreover, the payload decoding is not desired in some cases. Let's introduce the new fields, which will carry the raw unmodified payload, its length and DCS (Data Coding Scheme). Change-Id: Ia193d175021e145bb3b131290231f307dbefc64a

| | | | | | | | | | libosmocore has no value strings for BSSMAP cause codes yet. - Add value strings for BSSMAP cause codes and a function to retrieve them Change-Id: I313dd8d7b06374e1e35ddc18b7a42562d9e25d45 Related: OS#1609
* fix logging talloc ctx: add osmo_init_logging2()Neels Hofmeyr2018-03-282-2/+11
| | | | | | | | | | | | | | | Deprecate osmo_init_logging() for the benefit of adding an explicit talloc context argument to new function osmo_init_logging2(). Pass a ctx to log_init() instead of hardcoded NULL. Before now, *all* of our code uses a NULL ctx for logging, which amounts to talloc "leaks" hit by address sanitizer builds on newer gcc (e.g. gcc 7.3.0 on debian 9). This commit helps fixing "leaks" detected in e.g. osmo-bsc unit tests by a sanitize build with gcc (Debian 7.3.0-12) 7.3.0. Change-Id: I216837780e9405fdaec8059c63d10699c695b360
* vty/command.c: write_config_file(): sanely compose temp pathNeels Hofmeyr2018-03-281-1/+11
